Issues with still image files in the latest update
I just had to roll back from v22.0 to the previous v15.4.1
I was trying to load/replace jpg image files in the timeline and they all myteriously only apeared as one of the several images. So for example 1.jpg looked the same as 2.jpg even though they were definately quite different iamges. Weird and imposoble to work around. In v15.4.1 I had it open the imahes in another image editor then save. But then they all apreared corectly - I assume that was only because of a bug V22.0 left on the sequence file.
I recomemend not updating till they have fixed or explained this weird bug.
